Answer:
4 mol of Al₂O₃ are produced from 8 mole of Al
Explanation:
The reaction:
4 Al + 3O₂ → 2Al₂O₃
Ratio is 4:2
So, If we have 8 mol of Al, we will produce 4 mol of Al₂O₃
Answer:
6.6 x 10⁻⁵ mol/L
Explanation:
First, we have to convert the moles from μmol to mol:
moles of solute= 33.0 μmol x (1 x 10⁶ mol)/1 μmol = 3.3 x 10⁻⁵ mol
Then, we convert the volume from mL to L:
volume = 500.0 mL x 1 L/1000 mL = 0.5 L
Finally, we calculate the concentration of the solution in mol/L by dividing the moles into the volume in liters, as follows:
mol/L = moles of solute/volume = 3.3 x 10⁻⁵ mol/(0.5 L) = 6.6 x 10⁻⁵ mol/L
Answer: <span>Ethanoic acid (CH3COOH)
Reason:
Chemical property of substance depends upon the functional group associated with the system. Compound with same functional group will have similar chemical properties.
In present case, </span>propanoic acid has an acidic functional group (-COOH). Also, ethanoic acid has an acidic functional group (-COOH).
On the other hand, propanal and1-propanol have aldehydic (-CHO) and alcoholic (-OH) functional group. <span>Propane is a pure alkane and will have minimum chemical reactivity.
Due to this, propanoic acid will have chemical properties similar to ethanoic acid. </span>
